Yaskawa AC Drive P1000 Bypass Technical Manual - Manual (Page 356)

G.1 N2 Specifications and Configuration
The bypasses can be monitored and controlled by a controller on a Metasys N2 network (N2) using RS-485 technology. The
bypass act as slaves on the N2 network.
Up to 255 bypasses can communicate on a single N2 network. If more bypasses or N2 devices are required, another N2 network
is required.
The N2 node address is configurable by a parameter in the bypass. This defines the physical address of the bypass on the N2
network.
Once the addressing is set, a controller can initiate communication to the bypass. The bypass will perform the specified function
and then send a response back to the controller.
